Abstract: In a communication method, a first communication apparatus obtains first configuration information of a first signal, where the first configuration information is associated with a first communication procedure of the first communication apparatus. The first communication apparatus obtains second configuration information of the first signal, where the second configuration information is associated with a second communication procedure of the first communication apparatus. The first communication apparatus sends the first signal based on at least one of the first configuration information or the second configuration information. In this way, the first communication apparatus can use a same type of signals to perform different communication procedures. This reduces processing complexity, and can further reduce chip costs of the first communication apparatus and improve resource utilization.

Abstract: A first access network device (AND) sends a first message to a second AND. The first message is usable to request to hand over a group of terminal devices under the first AND to the second AND. The group of terminal devices includes one or more terminal devices. In response to the first AND receiving a first response message from the second AND for the first message, the first AND sends a second message to the terminal devices. The first response message is usable to indicate that the terminal devices are allowed to be handed over to the second AND, and the second message is usable to indicate the terminal devices to be handed over to the second AND. After the terminal devices are handed over to the second AND, the first AND switches off one or more cells.
